Application filed March 26, 1913. Serial No. 756,990.

To all whom it may concern:

Be it known that I, NORMAN W. CUM arms, a citizen of the United States, residing in the city of Bridgeport,'cou1ity of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Grease-Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains. to. make and use the same.

This invention relates to certain new and useful improvements in grease cups, and pertains more particularly to the head construction thereof. i

The object of the invention is to provide an improved structure in which the head of the body is reinforced to allow of the cutting of threads thereon without danger of distortion, weakening or otherwise affecting the structure in the operation of threading.

A further object of the invention is to provide an improved form of reinforcement, and novel means for connecting same to the body ,of the cup.

In. the drawingszFigure 1 is a vertical sectional view of the completed cup; Fig. 2 is a bottom plan view; Fig. 3 is a side elevation of the body prior to the reinforcement thereof; Fig. 4; is a section on the line if-"4 of Fig. 5; and Fig. 5 is a top plan view "of the reinforcing member.

i The body 1 is preferably of hexagonal cross-section, though same may be of other form, angular or otherwisc,'if desired. The lower end of the body has a reduced exterior part 2, which in the completed cup is exteriorly threaded asdepicted in Fig. 1, and has an outlet 3, illustrated in Fig. 2. The upper end of the body is provided with an annular outwardly extending flange i, which is engaged with a flange 5 that extends on the interior of the reinforcing member 6 at the base end of the latter. The

reinforcing member 6 is of substantially cup-shape and its flange 5 is formed with a hexagonal opening 7 that conf'ormably en gages over the hexagonal body 1 and isthereby held against rotation; After the reinforcing member 6 has been placed on the body 1 so that its flange 5 engages the flange l of the body, the upper or free end portion of the cupshaped member 6, is spun or forced inwardly and downwardly to clamp the flange 4: between the flange of the body and the inturned flange 8 that is formed by bending the free end portion of the member 6 inwardly, as just described; The peripheral portion of the member 8 is then threaded to receive the closure cap 9.

By use of the present invention, it will be seen'that the head of the body is greatly reinforced and that the threading of said head can be accomplished without danger of in jury thereto. Further, since the periphery of the flange 4: of body 1, snugly fits against the inner circumference of the member 6, the latter is braced and strengthened, as clearly seen in Fig. 1.

What is claimed is:

1. In a grease cup, :1. body of angular cross-seetionhaving an outwardly extending flange at its upper end, a cup-shaped reinforcing member having an inwardly extending flange which latter is formed with an angular opening that receiv s said body, the flange of said member abutting the flange of the body, the free end of said memher being extended inwardly to abut the flange of the body, the peripheral portion of said member being threaded.

2. In a grease cup, a body having an out- NORMAN 'W. CUMMINS.
